In a bizarre match where the Saints took an age to get going, North blew a 20-point lead in the second quarter as St Kilda went on to score 62 points in an unbroken run.

An end to that torment finally came when Daniel Wells goaled midway through the third quarter, but by that point the Saints were well on their way and the broken Kangaroos only managed two more goals for the rest of the night.

Young Kangaroos midfielder Jack Ziebell was reported for a high bump on Riewoldt in the third quarter and team-mate Levi Greenwood also had his number taken for a high hit on David Armitage during the second term.

Kangaroos coach Brad Scott blasted the process of match-day reports.

"The whole reporting on the day of the game needs to be completely just thrown in the bin because it's a complete waste of time," Scott said.

"The match review panel deals with that, the video review deals with that and we've seen instances this year where umpires make mistakes, the match review panel throws it out, but you still get a free kick played against you."

Scott said he knew nothing of television and radio reports that captain Brent Harvey had complained to the umpires at half-time abut an onfield incident.

"'Boomer' (Harvey) hasn't said anything to me," Scott said.

Scott admitted poor defensive efforts late in the second quarter allowed the Saints to get back into the game and the Kangaroos were simply outrun in the last half.

"Their run was terrific," Scott conceded.

"They proved they're a better side than us right at the moment, we know we've got a lot of hard work to do."

With its finals hopes over, North plays Richmond next Sunday at Docklands while the Saints face Carlton in a Saturday blockbuster at the MCG.
